This week­­­­­­ you need to make sure you have a clear idea of the 4 different types of solids: metallic, ionic, covalent networks and molecular. The properties of each and be able to explain the properties using your knowledge of the particular structure.

In the attachments there are some NCEA questions on the topic. I will post the answers later in the week and we can discuss in the VC session.

The 2nd part of the week, you will start the 3rd component of this standard, “Energy changes”.

To do:

·         Worksheets 3, 4 and 5 in the attachments.

·         NCEA questions in attachments

·         Read p135-138 in the study guide. In your notes

1.       write a definition for an exothermic reaction and draw an energy level diagram

2.       write a definition for an endothermic reaction and draw an energy level diagram.

3.       Write a definition for enthalpy and write the equation for enthalpy change (DH).

4.       Do Act 11B
